What is the name of Keenan Wynn's playwright character in 'A World of His Own'?

In “A World of His Own,” Keenan Wynn plays the playwright Gregory West.

Gregory is a successful writer whose spoken descriptions, recorded on a dictaphone, can bring fictional characters and objects into existence. His wife, Victoria, suspects him of infidelity after seeing him with a woman named Mary, but Gregory makes Mary disappear by destroying the recording that created her.

The episode turns authorship into a literal supernatural power: Gregory can create people, erase them, and even summon an elephant to block Victoria from leaving. The story’s playful tone distinguishes it from the darker episodes surrounding it in the first season.

“A World of His Own” aired on July 1, 1960, as season one’s finale. Richard Matheson wrote the teleplay, and Rod Serling makes an unusual on-camera appearance near the ending. Rocky Valentine, Walter Bedeker, and Martin Sloan are characters from other Twilight Zone stories, which makes them tempting but incorrect alternatives.
